iBe it known that I,`DAIELSG. CHASE, of Bo's'tom'in the county of Suffolk, and State of Massachusetts,

Vhaveinyented a new 'andv useful Improvement in Shuttles;l and do hereby declare the following to be a full, clear, and exact description theredf, due referenceV beinghad t the accompanyingV drawings, making part of this specification, and in which-- I Figure 1 nisa vertical and longitudinal section-of a shuttle4 containing my invention. Figure 2, a side elevation; and l I v i shuttle.`

. 'The object of this invention is to facilitate the insertion or. the removal of a shuttle-bobbin, and to adapt a shuttle to theuse' of bobbins having different-sized heads, as well as to maintain the bobbin and'spindle at all 'times in its proper position; a `s till further object-of the'invention,'and by nomeans an unimportant one, being the simplicity and eheapness with which Vthe device may be made.- A

The invention consistsin `the peculiar application of espiral or coiled spring to the heel of the bobbin- Fgnre 3, a top view of thebobbin-spindle. with ythefattached springs, as removed from the-body of the .spindle,.and in combination with an extended or eloingatedl heel of such spindle, to which a dat bobbin-spring is applied, substantially ashereinafter referred to and explained.

In' the drawings before'mentioned, A denotes the body of ashuttle constructed in the ordinary manner Thebobbimspindleisshown 'at a, `as supported and turning upon a horizontal pinfb, extending through'it and -the shuttle, the said spindle having an elongated head', @extending backward from it, this head c being hollowor made with a longitudinal slot', d, through it, a plate-spring, e, being'secured at one end to the extremity of the under side 'of the -h'ead,and extending forward a short distance in advance ofthe bolsterf of such' head, Vthe spring, at this point, being given an upward bend, in orderto iit into the groove formed in the head ofthe 'b`obbin, and retain such hobbinin its-.due relation to the shuttle. A pin`or stud, y, is passed transversely through the shuttle and immediately abovethe spring e, to form a stop or check to the movement of such lspring as the s'pindleis turned upon its'fnlcrum from a horizontal' into an angular position, by this means increasing this distance between the free end ofthe spring andthe bolster of the spindle, and byso doingremovc the hold of dsuch 'spring'upon the headloithe bobbin, and allow it'to be withdrawn from the shuttle or the spindle.'

Forfretracting .the bobbin-spindlehback into-its horizontal' position within the shuttle, make use cfa coiled spring, shown'at h in the drawings, one end'of such'sprin'g. being attached to thehead of the spindle'` Vimmediately in rear of' its bolster, and the opposite en d of such springlbeimgg secured to a pin, z', extending laterally 'through the lshuttle and-over the. onter vor free end of( the extended `spindle-head @,the body ofthe spring h beingdisposed' within the 'opening or slot of such' head, asshown in'g. 1 of the drawings.

' 'It will .readily ,be 4seen that as the-spindle a is moved out of line of axis of the shuttle, in the act off. removing the bobbin, uponbeingleft free, the coiled spring will, by its contractile power, return it instantly to place,` the extremityof the head e' bringing upnagainst a bearing1 j, made within the body of the shuttle; I v -By the arrangement of the'plate-spring e with respect to theistationary ping and the bobbin-spindle, the bend .of .such spring, as 'the spindle turns'upon-itsiilcrum, does not bind or catch upon the head ofthe bobbin, but following the movements of; the spindlefto such an extent, until itrecedes therefrom, as to free the bobbin without friction upon n. l q

i When a cop-shuttle'is'to bev employed,` in'stead of a bobbin-shuttle, thespring e is to be omitted.

I claini the combination ofthe open slotted 'spindlediead c,coiled'sprin`g h, and plate-spring e, with the shuttle A and stop-pin g, the whole being constructed and arranged fornaci-ation, as herein shown and described.
